发送一个 arraylist 到 parent activity

Question

我想发送一个 arraylist 到 parent activityprivate ArrayList<Receipt> receipts = new ArrayList<Receipt>();  Intent data = new Intent();  data. // what to do here? setResult(RESULT_OK, data);  //************************************下面是简单的代码public class Receipt {     public String referenceNo;     public byte[]   image;     public String comments;     public Date   createdOn;     public Date   updatedOn;如何在 intent 中添加，还有如何从 parent activity 里检索？onActivityResult(final int requestCode, int resultCode, final Intent data)

Answer 1

public class Receipt implements Serializable{
    public String referenceNo;
    public byte[]   image;
    public String comments;
    public long   createdOn;
    public long   updatedOn;
    //...
}

//Put the list in the intent
List<Receipt> list = ...
Intent data = new Intent();
data.putExtra("tag", list);

//Read the list from the intent:
list = (List<Receipt>) data.getSerializableExtra("tag");

Answer 2

Receipt extends Parcelable才能传递

public void putParcelableArrayList(String key,
        ArrayList<? extends Parcelable> value) {｝
